The distance from the top of the statue to Ezra's head is 9.4m
Application of Pythagoras theoremThe theorem states that the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given the following
Height of statute a = 5mDistance of Ezra from the statute = 8mRequired
Distance from the top "c"
According to the theorem;
c² = 5² + 8²
c² = 25 + 64
c² =89
c = √89
c = 9.43m
Hence the distance from the top of the statue to Ezra's head is 9.4m

Please help me! thanks
Answer:
1) 16
2) 20
3) -12
4) 16
Step-by-step explanation:
1) Substitute the r for 4 like it tells you in the question so 12 + 4 = 16.
2) Substitute d with -3 so 5(-3+7) = 5 x (4) = 20
3) Substitute m for 4 so -48 / 4 = -12
4) Angle of triangle is half base times height or 1/2 x b x h
And since the base is 4 and the height is 8:
1/2 x 4 x 8 = 1/2 x 32 = 16
Or in other words:
1/2 x 32 = 32 / 2 = 16
All of the following are equivalent to 2(2a + b) + 8, except _____.
A. 4 a + 2 b + 8
B. 4( a + b + 2)
C. 4 a + 2( b + 4)
Answer:
B. 4( a + b + 2)
Step-by-step explanation:
Task: Simplify 2(2a + b) + 8
1. Distribute the 2
4a + 2b + 8
---------------------
Evidently, that is the same as A, so A is correct.
Now if we try C, 4a + 2(b+4), we see we need to simplify to check.
So let us distibute the 2.
4a + 2b + 8. Also correct.
This probably means that B is incorrect.
4(a + b + 2)
Let's distribute the 4.
4a + 4b + 8
This is incorrect because only have two "b".

how do you graph this equation?
Step-by-step explanation:
10 = 0.5n + 1.5
0.5n + 1.5 = 10
0.5n x 10 + 1.5 x 10 = 10 x 10
5n + 15 = 100
5n + 15 - 15 = 100 - 15
5n = 85
5n/5 = 85/5 Divide both side by 5)

Using the triangle below, set up and solve an equation in order to find the value of x.
Answer:
x = 180 - 118 - 34.6 = 27.4
Step-by-step explanation:
The sum of the internal angles of each type of (2D) polygon will only have 1 specific value for each polygon. In the case of a triangle, the interior angles add up to 180 degrees.
Using a statement-reason approach, we start by saying:
Q^ + R^ + S^ = 180 degrees (*) Interior angles of a triangle = 180
(*Please use proper notation if you were already taught it - these computer keyboards can only do so much you know...)
Then you just solve normally for x:
34.6 + 118 + x = 180
x = 180 - 118 - 34.6
x = 27.4 degrees

→ 48 text messages
Step-by-step explanation:
Were being asked how many text messages are to Bianca. Today, were using 3 ways on how to solve this problem. 2 are incorrect and 1 is correct.
First, let's use addition.
[tex]120+\frac{4}{5} +\frac{1}{2} =121.3[/tex]
Were not looking for 121.3, it's too high. Therefore, using addition is incorrect.
Second, let's use subtraction..
[tex]120-\frac{4}{5} -\frac{1}{2} =118.7[/tex]
Were not looking for 118.7 either. Therefore, using subtraction is incorrect as well.
Third, let's use multiplication...
[tex]120 * \frac{4}{5} * \frac{1}{2} = 48[/tex]
As a result we got 48. Which is the answer your looking for.
Hope this helped! :^)

Here it is: 20% of a number is x. What is 100% of the number? Assume x > 0.
Answer:
5x is 100% of the number.
Step-by-step explanation:
100/20=5%
5*x=5x percent.
x is 20% of Number
x = (0.2) x (number) .
Divide each side by 0.2 : Number = x / 0.2
Number = 5x .
'x' can be anything, even zero. This equation works for x=any number.
